RCA 721TS mouse house

[Zenith6S321]

I thought it was a good price, but was not sure with all the veneer damage. I found what I think may be a date on the rebuilt tube socket at its very end (the keyway part of the socket). Its a circle with a "59" on top and a "22" on the bottom. I suppose that could be the 22nd week of 1959? It is the same blue colored ink as the RCA Monogram lettering.
